CPI VZC-6965B5

CPI 2.25kW TWT C-Band HPA
for Satellite Communications
C - Band
The VZC-6965B5
2.25kW TWT
High Power
Amplifier features
high efficiency, small
size and an integral
computer interface.
Compact
Provides 2250 watts of power in the
5.850-6.650 GHz frequency band in a compact
19-inch rack-mount dual drawer configuration,
digital ready, for wideband, single- and multicarrier commercial satellite service.
Efficient and Reliable
Integrated microprocessor control lets the user
adjust and monitor all operating parameters
from one easy-to-read local or remote panel,
using straightforward menu-driven commands.
Includes a built-in interface and serial bus for
operation from the station computer.
Easy to Maintain
Modular design provides for easy installation
and maintainability in the field.
Worldwide Support
Backed by over three decades of satellite
communications experience, and CPI’s
worldwide 24-hour customer support network
that includes sixteen regional factory
service centers.
Safe
Meets International Safety Standard EN60215
and EMC Standard 2004/108/EC to satisfy
worldwide requirements.

2.25 kW TWT High Power Amplifier
Simple to Operate
C-Band
Employs a CPI dual-depressed collector helix
traveling wave tube which increases efficiency
by a nominal 20% over conventional single
collector TWTs, and a power supply designed
with a minimum number of parts for
maximum uptime.
